What happens when light passes through concave and convex lenses?
When light passes through a concave lens, it diverges or spreads out. This results in the formation of a virtual and upright image. On the other hand, when light passes through a convex lens, it converges or comes together. This leads to the formation of a real and inverted image.
What bends light inward?
A concave lens or a denser medium bend light inward. This bending effect is known as refraction and is caused by the change in speed of light as it passes through different mediums.
How does light refracts as it travels through a concave lens?
As light passes through a concave lens, it refracts outward, causing the light rays to diverge. This is because the concave lens is thinnest at the center, causing the light waves passing through it to spread apart. The point at which the refracted light rays appear to converge is known as the focal point.
How does light behave as it passes through a concave lens and a convex lens?
Light passing through a concave lens will diverge and spread out, leading to a virtual image formed. In contrast, light passing through a convex lens will converge towards a focal point, forming a real or virtual image depending on the object distance.
Why is the concave spoon turns upside down?
A concave spoon will appear to turn upside down when immersed in a liquid due to the refraction of light. When light passes from air into a denser medium (like water), it bends and changes direction. This bending of light causes the concave spoon to appear inverted when seen through the water.

What happens to light that passes through a convex lens?
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.

Explain What happens when a beam of light passes through a colloidal solution and why?
When a beam of light passes through a colloidal solution, the light scatters off the suspended particles in the solution in all directions. This scattering of light is known as the Tyndall effect. The intensity of the scattered light depends on the size of the particles in the colloidal solution.
What is the difference between the way parallel light rays are affected by a concave mirror and a concave lens?
The difference between the two is that once the light passes through the concave lens it diverges, and the rays are refracted outward, and never meet a focal point. Then there is the parallel light rays that bounce off the curved surface of a concave mirror and then meet a single point ( focal point).
What effect does concave lens have on the parallel light rays passing through it?
A concave lens will cause parallel light rays passing through it to diverge or spread out. This is because the lens is thinner in the middle than at the edges, causing the light rays to refract in a way that makes them spread apart.
What type of Len's convex or concave does a prism act like?
A prism acts like a piece of glass that has two flat, non-parallel surfaces. Each surface of a prism behaves like a lens - one surface is concave and the other is convex. The combined effect of these surfaces is to bend light as it passes through the prism.
When a light passes through a prism it spreads into a spectrum of colours what is spreading effect called?
The spreading effect when light passes through a prism and separates into different colors is called dispersion. This occurs because different wavelengths of light are refracted by different amounts as they pass through the prism, causing them to spread out into a spectrum.
What is the name of the effect when light goes through glass but changes direction?
The name of the effect is refraction. Refraction occurs when light passes through a medium such as glass and changes its speed and direction, resulting in bending of the light rays.
